Psalm 132:11
The LORD swore to David a sure oath
from which He will not turn back:
"One of the sons of your body
I will set on your throne."
Sacramentum is the Latin word for "oath." It is worth noting that the sacraments are God's oath to us, as well as our oath to God. God swore an oath to David that one of the sons of his body — not his disembodied spirit — He would set on David's throne. That oath is ultimately and completely fulfilled in Jesus, the Son of David, who offers us His Body and Blood, not just His Spirit, in the Blessed Sacrament, the Sacrament of Sacraments and Oath of Oaths. Because Jesus shares our body and blood, He is able to redeem us not just "spiritually" but completely, right down to our toes. Because of this, we await, not just the redemption of our spirits or souls, but the redemption of our bodies when we shall share in His risen life. Come, Lord Jesus!
